Carbon steel bars are widely used in various fields, such as petroleum, chemical, building materials, and power industries. Carbon steel has properties of high hardness, strength, wear resistance, and anti-corrosion.

C45 carbon steel bar is a type of medium carbon steel bar with a carbon content ranging from 0.42% to 0.50%. Compared to low carbon steel, it has a higher carbon content. This increased carbon content enhances its hardness and strength, making it highly suitable for applications that require high mechanical performance.

A36 carbon steel bar has a carbon content of approximately 0.26-0.29%, which makes it relatively low in carbon compared to other carbon steel grades. This low carbon content contributes to its excellent weldability, as it can be easily welded without the risk of brittleness or cracking.

S2345JR is a hot rolled non-alloy structural steel. It has good plasticity, toughness, and weldability, moderate strength, and good cold bending properties.

SPCC carbon steel bars have excellent formability and are suitable for applications that require precise dimensional tolerances and a smooth surface finish.

SS400 carbon steel bars are versatile and have excellent weldability and machinability. They are widely used in general structural applications, such as beams, columns, bridges, and machinery parts. These bars are typically available in various shapes, including round, square, flat, and hexagonal.

Carbon steel flat steel bars are steel bars with flat and rectangular cross-sections, making them easier to manufacture and process
